JOHN T. OGDEN, OF BOSTON, MASSACHUSETTS.

I-IANLDE FOR VISES.

Specification of Letters Patent No. 14,366, dated March 4, 1856.

To all whom it may concern:

y Be it known that I, JOHN T. OGDEN, o Boston, in the county of Suffolkand State of Massachusetts, have invented a new and Improved Handle forOperating the Jaws of Vises, of which the following is a full, clear,and exact description, reference being had to the annexed drawings, inwhich- Figure l is a plan of a vise with my improvement; Fig. 2, a rearview o-f the same; Fig. 3, a longitudinal section through the same.

In vises as ordinarily constructed when the handle passes through thehead of the screw, it often happens that the handle is in the way eitherof the article to be operated upon or of the body of the workman, toavoid which inconvenience is the object of my present invention whichconsists in uniting the handle to the screw head by means of a swiveljoint, by means of which the handle may be turned in either direction ina plane perpendicular to the axis of the screw as readily as in the oldvises, and in addition it may be thrown into a position parallel withthe screw, or making any desired angle therewith.

To enable others skilled in the art to understand my invention I willproceed to describe the manner in which I have carried it out.

In the accompanying drawings A is the stationary; B the movable jaw, thelatter being attached to and making part of the sliding bar C, which isslotted longitudinally through its center to accommodate the screw D,and its nut E, the latter together with the stationary jaw A, beingsecured to the bench F, by the screw G. The screw D, is secured to themovable jaw. by the flange a,

and screw b, or in other suitable manner, so that the jaw shall movelongitudinally with the screw in either direction, while the latterrevolves freely within the jaw.

The handle H is forked at g, a pin f, passing through the fork and thesphere I, upon the screw D. A flexible joint is thus produced betweenythe handle and the screw head, which enables me to revolve the handleupward of 180o in planes passing through the axis of the screw. Thehandle may t-hus be operated or placed out of the way of the opi eratoror his work in a great variety of positions which t-he handles of visesas heretofore constructed are incapable of assuming.

In large vises for heavy work the handle has been made detachable fromthe screw head and is inserted when the vise is to be operated, and laidby after the object has been clamped; this is objectionable for thereason that the handle or lever used for the purpose has to be soughtfor among the tools upon the bench each time it is required7 whichoccasions considerable delay and loss of time. My improved handle is notliable to the above inconvenience while it equally with the detachablelever removes those objections, to which the old vise handle is liable.

What I claim as my invention and desire to secure by Letters Patent is-Uniting the vise handle with the head of the screw, by means of theswivel joint op erating in the manner substantially as herein set forth.
